Israel Antiquities Authority is the organisation responsible for all the antiquities of the Country, including the underwater finds.

Its Marine Archaeology Unit (MAU) is responsible for underwater archaeology along Israel’s Mediterranean coast, in the Sea of Galilee, the Red Sea, and the Dead Sea. The IAA’s marine archaeologists perform hundreds of dives each year. Their excavations include shipwrecks, ancient harbours, and submerged prehistoric settlements.      

The Herodian harbour of Caesarea, (Hof Hacarmel Regional Council, Israel): remains of the harbour of the ancient city of Caesarea Maritima, built by Herod the Great, the king of Judea, in 21 b.C. It represented an engineering marvel and consisted of two massive underwater barriers.

Between 3 and 8 meters below sea level.

The harbour is well-preserved, with many of its main components clearly visible, such as the breakwaters, the wooden caissons used for the foundation, and the hydraulic cement casting.
